![]() ![]() Parameter setting and each column is a tuning parameter. A data frame is used where each row is a tuning The tuneGrid argument is used when specific Integers between 1 and 15, setting tuneLength = 15 wouldĪchieve this. In the case of PLS, the function uses a sequence of Parameter values and the tuneLength argument controls how The train function can generate a candidate set of TuneLength or tuneGrid arguments can be used. To change the candidate values of the tuning parameter, either of the Here, theįunction will be altered to estimate the area under the ROC curve, the Root mean squared error and R 2 are computed. If unspecified, overallĪccuracy and the Kappa statistic are computed.
